PowerBatch
Computing Systems Design, Inc.
P.O. Box 566484
Atlanta, GA 30356-6009
There are 19 files on your installation disk. The two files SMLMODEL.MDL and
POWERMAK.EXE will be placed in a directory on your DOS search path. The
remainder of the files may be placed in any directory you desire. The
POWERBAT.DOC file is the documentation and may be viewed with any text editor
or printed to your printer with the DOS print command (ie print POWERBAT.DOC
<enter>). The files with an extension of .PWR are PowerBatch source files and
the text is printed in the documentation. You should compile these example
files and run the resulting programs to help familiarize yourself with
PowerBatch. The file DEMO1.PWR uses all the commands with a couple of
exceptions.
To install PowerBatch run the install program located on the source disk. If
the source in on a floppy drive enter A:PBINSTAL (or B:PBINSTAL). If the source
is on a hard drive, change directory to the directory containing PBINSTAL and
enter
PBINSTALL <enter>

If you have purchased a registered copy of PowerBatch, the install program will
recognize this by the presence of REGISTER.EXE on your diskette. When this
program is present, the copy of PowerBatch you have just installed will be
registered in your name.
Your name and serial number will be imbedded in the software by the
registration program. If you give anyone an evaluation copy of PowerBatch, DO
NOT PROVIDE THE REGISTRATION PROGRAM WITH THE EVALUATION COPY. Simply copy all
of the files but REGISTER.EXE. Better still, compile the two PowerBatch source
files PBCLONE.PWR and MOVESUB.PWR and use these to create a clone of
PowerBatch. PBCLONE uses MOVESUB as a subroutine and is an example of the use
of subroutines in PowerBatch. Anyone who uses the registration program
REGISTER.EXE will imbed your name and serial number within their software.
